The L treatmentThere are a few reports out there that Canon will finally replace the TS-E 45mm and TS-E 90mm in 2013. We should expect a replacement announcement in Q2 of 2013. Both of these lenses have long been rumoured to be on the replacement docket. No one has come out and said they’ll be “L” replacements, but I think it only makes sense. This would give Canon the largest high end tilt-shift lineup on the market.

Also mentioned in the same announcement breath, was Canon answer to Nikon’s 14-24 f/2.8. A very long awaited lens.

I really like the perspective of a normal lens and have been toying with the idea of getting a 45mm ts-e for some creative uses. However, the lens is still expensive and pretty soft. It softer than the 24-70 version 1, way softer than the 50 1.8 even at f/2.8. I'm hoping they make it as good or better than the 50 1.4 at 2.8 and beyond.

I believe that perspective is only affected by moving the camera, not by changing lenses."Many will say that focal length also determines the perspective of an image, but strictly speaking, perspective only changes with one's location relative to their subject."http://www.cambridgeincolour.com/tutorials/camera-lenses.htm

Yes, but a lens that is roughly equivalent to the diagonal of the sensor will yield images that look normal because it's similar to the way we see the world with our own eyes. For full frame this is close to 50mm. The lens isn't wide angle or tele.... I used perspective instead of field of view because we tend to fill the frame with our subjects. On wide angle this means we get closer than normal and with tele's we get farther away than normal.

Me neither, I am slowly switching to Nikon because of the superior image quality. (I am shooting low-iso only)But, with almost twenty canon lenses that is a big step for mankind, and some of the Canon lenses are better than the Nikon alternetives....
